  The size and shape of your ears show your character more than any other

part of the face. Other parts of the face change shapes as we get older, but ears

do not change their shapes. They only change in size.

Reading people's character from their ears is a very old science. In the past

people thought that a person's ears with color were dangerous. They also thought

that the shape of the ears showed if a person was musical or not. Today, too

many people believe that the size and shape of the ears help you know if a person

is musical.

  Ears are all different, and each different thing has a meaning. Next time you

look at a person, see if his or her ears are large, medium-size (中等尺寸), or

small. Look at the lobes(耳垂). Do they stick to the face? Ears that are always

red mean that a person may get angry easily. Ears that are always cold and nearly

white color mean that a person has a nervous character.

1. When we grow up, _____.

A. our ears will not change in size.  

B. our ears will be the same size.

C. our ears will get colder          

D. our ears will not change in shape.

A. he/she is a kind person.
